MPN: 19074

Barcode: 5028734190748

Size: 31.5mm (1 1/4") Flap Wheels, 3.17mm (1/8") Arbor

Weight: 0.09kg

Overview:

This Blue Spot Tools set contains seven 80-grit, 31.5mm flap wheels for grinding, polishing, and rust removal. Each wheel mounts via a 3.17mm (1/8") arbor and runs at up to 30,000RPM. The 80-grit abrasive flaps cut through surface rust and scale on metal. They suit applications where controlled stock removal matters, without stripping the workpiece aggressively.

A 3.17mm (1/8") arbor fits the standard collet found on most rotary tools. Seven wheels per set means you have a spare ready when one wears down.

What's Included

• Flap Wheels: 7 x 80 Grit 31.5mm (1 1/4")

Key Features and Benefits

• Grinding, Polishing, and Rust Removal: Each wheel handles all three tasks, so you do not need to swap between different abrasive accessories at each stage.
• Controlled Material Removal: The medium-coarse abrasive rating cuts through rust and scale while removing less base material than a coarser grit would.
• Fits Most Rotary Tools: The standard 1/8" arbor drops straight into the collet of most rotary tools - no adapters required.
• Full-Speed Rated: Wheels are rated for the maximum RPM output of standard rotary tools, so no speed limiting is needed during normal use.
• Spares Included: Seven wheels in the set mean replacements are ready without a separate purchase when individual wheels wear out.
• Compact Wheel Size: The 31.5mm diameter accesses tighter areas and smaller components that larger abrasive accessories cannot easily reach.

How to Use

• Fit the Arbor: Insert the 3.17mm (1/8") arbor into the rotary tool collet and tighten securely.

• Set Tool Speed: Set the rotary tool speed to no higher than 30,000RPM before starting.

• Start the Tool First: Switch on the rotary tool before bringing the wheel into contact with the workpiece.

• Apply Even Pressure: Hold the wheel against the workpiece with light, steady pressure and keep it moving consistently across the surface.

• Stop Safely: Switch off the tool and allow the wheel to stop completely before moving it away from the workpiece.

Frequently Asked Questions (FAQs)

• What is the difference between a flap wheel and a flap disc?
  A flap wheel has a cylindrical shape and is designed for use with a rotary tool or hand drill. It works well on curved, contoured, and hard-to-reach surfaces. A flap disc has a flat profile, fits an angle grinder, and is better suited to flat surfaces and heavier stock removal.

• How do I choose the right grit for a flap wheel?
  Lower grit numbers (40 to 60) cut more aggressively and suit heavy material removal. 80-grit sits in the middle of the range, handling rust removal, general grinding, and blending. Higher grits (120 and above) produce a finer finish and are better suited to polishing or light surface work.

• Can flap wheels be used on wood?
  Yes. Flap wheels can sand and finish wood, particularly on curved or irregular surfaces where flat sandpaper is harder to apply. The flexible abrasive flaps conform to the shape of the wood, making them well-suited to smoothing contoured or irregular timber.

• How do you know when a flap wheel needs replacing?
  Signs a wheel needs replacing include reduced cutting performance, visible wear on the abrasive flaps, and an inability to achieve the expected finish. Any visible damage to the wheel structure is also a reason to replace it before continuing work.

• Can a flap wheel be used with a power drill?
  Yes. Mounted flap wheels with a 1/8" shank can be used with a power drill that has a compatible chuck. Adjust the drill speed to a suitable level and maintain a firm grip throughout use.

Summary

The Blue Spot Tools 7 Piece Flap Wheel Set delivers seven 80-grit, 31.5mm rotary tool wheels for grinding, polishing, and rust removal on metal. Each wheel fits the standard 3.17mm (1/8") collet found on most rotary tools and runs at up to 30,000RPM. Seven wheels per set keep you working without the need for frequent replacements.
